The Koch brothers
Fred Koch left his company to four sons. Two of them spent the next two decades suing the other two over what it was worth. Their mother wrote a clause into her own will disinheriting any son still litigating six weeks after her death — and a Kansas court enforced it.
Fred C. Koch built an oil-refining engineering business in Wichita and died on November 17, 1967, leaving it to four sons: Frederick, Charles, and the twins David and Bill. Charles took over the company that year and renamed it Koch Industries after his father.
It is now among the largest privately held companies in the United States. It is also the subject of one of the longest-running family business disputes ever litigated in an American court.
In 1980, Bill Koch sought to change the control of the company and was removed from it. In 1983, Bill and Frederick sold their stakes to Charles and David. Accounts of the price differ — Forbes has reported it as more than $700 million, other accounts at roughly $1.1 billion.
In 1985, Bill and Frederick sued, alleging that the value of what they had sold had been misrepresented to them. That lawsuit, and its successors, ran for the next sixteen years.
A clause aimed squarely at two of her own sons
Mary Koch, their mother, died in December 1990 with an estate reported at roughly $10 million — small change relative to the company, and the source of the most consequential document in the whole saga.
Her will contained an anti-litigation clause: any son who was engaged in litigation against another son within a defined window after her death would take nothing.
Frederick and Bill were, at that moment, in litigation against Charles and David. They challenged the provision, contending among other things that their mother — who had suffered from dementia — had been unduly influenced into including it.
They lost at trial, appealed, and lost again. The Kansas Court of Appeals decision, In re Estate of Koch, 18 Kan. App. 2d 188 (1993), is now a standard citation on the validity of in terrorem provisions.
A no-contest clause worked exactly as designed, in a case where the money at stake in the will was trivial and the message was not. Whether Mary Koch's estate plan achieved peace is a separate question; it plainly achieved a forfeiture.
Nine weeks of trial, and nothing recovered
The central valuation case reached trial in the US District Court for the District of Kansas, in Topeka, in 1998. On June 19, 1998, the jury returned a verdict finding that the plaintiffs were not entitled to recover on any of their claims or theories.
Bill Koch pursued a separate line of litigation entirely — a qui tam action under the federal False Claims Act alleging that Koch Industries had under-measured oil taken from federal and Indian lands. A jury found in 1999 that the company had taken more oil than it paid for on thousands of occasions; the matter was resolved in 2001 with a reported $25 million payment.
In May 2001, Bill Koch and Koch Industries announced a settlement of all remaining disputes between them. After roughly twenty years, the family litigation ended by agreement rather than by judgment.
David Koch died in 2019. Frederick Koch died in 2020.
Note what the 1998 verdict did and did not establish. A jury heard the valuation case and found for the defendants on every claim — which means the plaintiffs failed to prove misrepresentation, not that the 1983 price was demonstrably right. A verdict allocates a burden of proof; it does not settle what a private company was worth fifteen years earlier. That is precisely why families litigate valuation for decades: there is no fact of the matter to find, only competing expert opinion about a hypothetical sale that never happened on an open market.
Which is the practical reason a written valuation method is worth so much more than it costs. A formula produces a number that is merely wrong. An argument produces a number that is merely expensive.
The exit is the part nobody drafts
Every element of this dispute traces back to one gap. Four people inherited a business together, and no document said what happened when one of them wanted out.
That is the ordinary case, not the exceptional one. Founders draft for succession — who runs it, who owns it — and almost never for divergence. Divergence is guaranteed. Children have different appetites for risk, different needs for cash, different views on whether the company should be sold, and different spouses.
What a buy-sell agreement supplies is not fairness. It supplies a method: an agreed formula or an appraisal process, an agreed timetable, an agreed source of funds, and an agreed forum for disputes about all three. When a family has one, the exit is an arithmetic exercise. When it does not, the exit is a valuation argument, and a valuation argument between siblings is a sixteen-year lawsuit.
The other lesson is about the anti-litigation clause, and it is uncomfortable. It worked in Kansas. It would not have worked in Florida. Whether that makes Florida better or worse depends entirely on whether the person contesting has a real case — which is the whole argument about no-contest clauses, compressed into one family.
There is a third lesson, quieter than the other two, about what an equal division of a private company actually gives each child. On paper, four sons received the same thing. In practice, two of them ran the business and two of them held pieces of paper whose value depended entirely on decisions the first two made. That is not equality; it is the same asset delivered in two completely different forms — a job and a lottery ticket. A plan that hands operating control to some children and passive minority interests to others has created two classes of heir, and it should say so out loud and price the difference.
The fix is neither exotic nor expensive. Where some children will run the business and others will not, the usual answer is to equalise outside the company — life insurance, real estate, retirement accounts, or a note — so the operating children receive the operating asset and the others receive value they can actually use. Where that is impossible, the alternative is a written commitment to distributions, information rights, and a defined exit, so a minority holder is not dependent on goodwill for the rest of their life.
Every one of those provisions is one page long. The Koch litigation ran for two decades because nobody wrote any of them in 1967.

What actually went wrong
- No buy-sell agreement. Four heirs, one private company, and no agreed method for one of them to leave. Everything else in this case is downstream of that omission.
- No agreed valuation mechanism. Where the document does not name an appraiser, a formula, or a process, the price becomes a matter of opinion — and opinions about a private company's worth differ by billions.
- Information asymmetry between owners. The shareholders running the company necessarily know more than the shareholders who are not. Contractual information rights and independent advice at the time of a buyout are what prevent that gap from becoming a fraud allegation fifteen years later.
- A no-contest clause used as a family instruction. Mary Koch's provision was enforceable in Kansas and forfeited real money. It did not stop the litigation. Penalty clauses tend to punish the outcome rather than prevent the behaviour.
- Two decades of legal cost against a fixed pot. Whatever either side thought it was owed, twenty years of federal litigation between people who share a surname consumes more than the disputed margin in almost every case.
Would it have gone that way in Florida?
Opposite result on the will. Florida would have struck the anti-litigation clause outright — and it would have done nothing to fix the actual problem, which was a missing buy-sell agreement.
Take the clause first, because Florida's rule is unusually clean. Fla. Stat. §732.517 provides that a provision in a will penalising any interested person for contesting the will or instituting other proceedings relating to the estate is unenforceable. Fla. Stat. §736.1108 says the same for trusts, including a provision penalising a beneficiary for challenging the trustee's acts or the trust's validity. There is no good-faith or probable-cause exception, because none is needed: the clause simply has no effect.
So the Mary Koch provision, transplanted to Florida, would have been read out of the will and the sons would have inherited whatever else it gave them, litigation or no litigation. Florida made this choice deliberately. The legislature concluded that a forfeiture clause deters meritorious challenges — the ones brought by a child who suspects a caregiver rewrote a document — more effectively than it deters speculative ones, because a person with a genuine claim usually has more to lose.
That does not leave a testator without tools. A well-drafted trust reduces contest exposure far more effectively than a threat: it avoids the public probate docket, uses shorter limitation periods, and can build in mediation or arbitration provisions and a trust protector under §736.1406 with power to resolve administrative disputes without a courtroom. The strongest anti-contest device in Florida is a document executed early, in good health, with contemporaneous evidence — not a penalty clause.
Now the governance problem, which is where the real money went. Florida's Trust Code assumes families will disagree and supplies the machinery. §736.0703 provides that co-trustees of a trust with three or more trustees act by majority decision, and allows a co-trustee to act unilaterally where prompt action is needed to achieve the trust's purposes and a co-trustee is unavailable. §736.0706 allows a court to remove a trustee — including where lack of cooperation among co-trustees substantially impairs the administration of the trust, or where removal is requested by all qualified beneficiaries, best serves their interests, is not inconsistent with a material purpose of the trust, and a suitable successor is available. An even number of equally empowered siblings is a deadlock; §736.0703 and §736.0706 are the statutory exits from one.
For the operating business itself, Florida law lets the family write the rules. §605.0105 gives an LLC operating agreement broad authority over relations among members, management, and transfer of interests, subject to a list of things it may not do; §620.1702 limits a transferee of a limited partnership interest to distributions only. Those provisions are what make a buy-sell agreement enforceable against a departing sibling, a divorcing spouse, or a creditor — and they only work if somebody writes the agreement.
The practical instruction, and it is the same one whether the company is worth $2 million or $20 billion. Put the exit in writing while everyone is speaking to each other. Name the valuation method — a formula, a named appraiser, or a three-appraiser process with a defined tie-break. Fund it, usually with life insurance or a defined instalment schedule, so a buyout does not require selling the business. Say what triggers it: death, disability, divorce, retirement, deadlock. And do not rely on a no-contest clause in Florida, because it is void here and it would not have prevented this fight in Kansas either.
